From the GPO:
The U.S. Government Publishing Office (GPO) has partnered with the Library of Congress (LOC) to make bill status information in XML format available through GPO’s Bulk Data repository on govinfo for the 113th and 114th Congresses. Bill status information, which is created by LOC and Congress, describes the activities and status steps for each legislative measure. This project commenced at the direction of the House Appropriations Committee, and is in support of the Legislative Branch Bulk Data Task Force.Making Government information available in XML permits data to be reused and repurposed not only for print output but for conversion into ebooks, mobile web applications, and other forms of content delivery, including data mashups and other analytical tools by third party providers, which contributes to openness and transparency in Government.
In addition to the files made available through the govinfo Bulk Data Repository, GPO ensures the authenticity of all information provided on govinfo by making available digitally signed copies in PDF format, which is the official, authentic version that matches the printed document.
